I have a question about the Gnome Alternate Racial Trait (Advanced Race Guide) "Master Tinker: Blah blah blah. They are treated as proficient with any weapon they have personally crafted. Blah blah blah." (http://paizo.com/pathfinderRPG/prd/advancedRaceGuide/coreRaces/gnomes.html )

If I understand the rules correctly, this should allow you to qualify for feats that require proficiency in a weapon, but you will only be able to use such feats with appropriate weapons that you have crafted yourself (unless you eventually pick up the proficiency elsewhere).

Am I correct in my understanding or not?

Edit: examples of such feats would be weapon focus, rapid reload, or siege engineer (ultimate combat)

An Example of what I am talking about would be: You, Bob, have this trait, craft a rapier, and take weapon focus rapier. Your weapon focus feat works just fine, but only with the one rapier you made yourself. But when you pick up your friend Tom's rapier, your weapon focus feat doesn't help you at all.
